LCAT7469-2

Overview

The LCAT7469-2 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in radio frequency circuits. It provides a nominal attenuation of 2 dB with a tolerance of ±1 dB. The component operates within a frequency range from DC to 12 GHz and maintains a characteristic impedance of 50 Ohms. It supports a maximum continuous wave power handling of 2 Watts. The unit features TNC connectors on both ends, configured as a plug-to-jack inline module. The maximum Voltage Standing Wave Ratio (VSWR) is specified at 1.35:1.

Feature Summary

• Fixed 2 dB attenuation value for precise signal reduction
• Wideband operation covering DC to 12 GHz frequencies
• TNC connectorized design for secure inline integration

Applications

• RF signal path attenuation
• Test and measurement equipment
• Telecommunications systems

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct attenuation value and connector configuration. Confirm that the required frequency range up to 12 GHz and power handling capacity of 2 Watts align with system requirements. Check datasheet specifications for VSWR limits and impedance matching to guarantee compatibility with existing 50 Ohm infrastructure.

Selection Notes

Select this component when a fixed 2 dB reduction is required within a 50 Ohm system operating up to 12 GHz. Ensure the application environment does not exceed the 2 Watt CW power rating. Consider the TNC interface type for mechanical compatibility with mating connectors. Validate that the ±1 dB tolerance meets the precision needs of the specific circuit design.

Part Context

This model belongs to the LCAT7469 series of fixed attenuators from L-com. The series offers various attenuation levels, including 9 dB and 20 dB variants, all sharing similar form factors and performance characteristics such as the 12 GHz frequency range and 50 Ohm impedance. These components are standardized for use in general RF applications requiring reliable signal attenuation.

Replacement Considerations

Compatible substitute part numbers include LCAT7469-9 for 9 dB attenuation and LCAT7469-20 for 20 dB attenuation within the same series. Verify that any replacement matches the TNC connector type and 50 Ohm impedance specification.
